I have a IV-P that is not done/not flying. The input I forwarded came from when I designed and machined new intercooler "end caps" for some new intercoolers I decided to use.

Some follow-up questions... Who set up your engine? Lancair? Did you (they) get any "official" input from TCM? Is there anything different in the waste gate (slope) controller or turbos? Do you have any special power reduction procedures? (i.e. reducing MP slowly to let Upper Deck Pressure bleed off) Do you have much experience with it up high (i.e. 25,000 ft)? Perhaps the banter regarding compressor stalls with the sonic nozzles plugged is OWT (Old Wise Tale). However, know of several straight IV's (non-P) that still have sonic nozzles because they were told they needed them???

Craig,
Thanks for the = info!  Some follow-up questions...

Who set up your = engine?  Lancair?  Did you (they) get any "official" = input from TCM?  Is there anything different in the waste gate = (slope) controller or turbos?

Do you have any = special power reduction procedures? (i.e. reducing MP slowly to let = Upper Deck Pressure bleed off)

Do you have much = experience with it up high (i.e. 25,000 ft)?

Perhaps the banter = regarding compressor stalls with the sonic nozzles plugged is OWT (Old = Wise Tale).  However, know of several straight = IV's

(non-P) that still = have sonic nozzles because they were told they needed = them???
